LM4765 Datasheet | National Semiconductor

Description The LM4765 is a stereo audio amplifier capable of delivering typically 30W per channel of continuous average output power into an 8Ω load with less than 0.1% (THD + N). Each amplifier has an independent smooth transition fade-in/ out mute and a power conserving standby mode which can be controlled by external logic. The performance of the LM4765, utilizing its Self Peak Instantaneous Temperature (˚Ke) (SPi Ke™) Protection Circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPi Ke Protection means that these parts are safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and instantaneous temperature peaks.
